    Audio with carputer is not comparable to decent head unit...

    Certain audio sounds muffled at times... we are using stereo out that is split to the amps and then out to the speakers and sub. 5.1 is basically pointless to even use with Windows 7 and the onboard Realtek because speaker fill is complete ****.

    We had issues with the Realtek drivers and Windows XP so we ditched XP. Also ditched XP because of some hibernation issues.

    What are your guys audio setups?
    How would you correctly and permanently set and adjust the volume so the audio going from the carputer to the amps doesnt turn everything up to insane volume levels with only a couple notches on the volume slider?

    Is anyone using any type of preamp as their audio volume control?

    sounds like you have some sound issues. what motherboard are you using?

    have you thought about upgrading your audio? USB or PCI.
    there are a lot of options that can give you much better results.

    I love that option but going with a 6 channel setup (5.1) means that we have to spend a junk load of money on those preamps. Those things are tits... but... $$$ =(

    i ended up buying 5 of 'em for a total of nearly $300(gasp) (one was defective after the 7 day ebay return policy...)

    for multi channel audio, there is only a couple of higher quality options-- either a audiocontrol unit @$160:
    http://www.sonicelectronix.com/item_...ix+-GRAY-.html

    a couple of 2 channel ones @$30 each(there are different options for this, i'll list one):
    http://www.sonicelectronix.com/item_...old+TLD22.html

    most are good options and should work great for most people, but the entire reason that i went with the cl-rlc's is because i wanted a phyiscal, immidiate, 6 channel, volume control adjustment that the windows control did not allow for. (i like it loud, but try to be courteous at lights, which means that i turn it down at stoplights, and the windows volume control was too sluggish, and slow to reliably do that-- i would still be working on turning it down as the light turned green, and then be distracted for the next 20 seconds getting it back to the level i wanted...).

    i even thought about getting a audiocontrol unit, and then extending the adjustment knobs to the front seat to do it cheaply, but became worried about the extra resistance of the added lenth of wire, and how it could affect the preamp...

    afte pouring over all sorts of options, i could not find a solution to a mutichannel volume control other than the cl-rlc. i was open to having a separate preamp, and volume control (the volume controls that i found all required me to loop audio cables from the trunk, to the dash and back-- i felt that was uneccesary), but could not find anything.

    so, i had little choice but the cl-rlc...

    5.1 in a car is pointless, and windows 7 or vista is lightyears ahead of xp in terms of audio processing. also, current realtek onboard sound chips like the ALC888 are just as good as many home theater receivers when paired with windows vista or 7.

    Buy a decent sound card (see FAQ), with at least 2V outputs, and place it close to the amp
    (use short rca cables), avoid ground loops, and shield everything well.

    Some guys even using carPC on SQ competitions, so with proper install and high-quality parts,
    you will not notice any difference between a headunit (with sound processor) and a pc.

    I think a decent carPC can compete with a decent headunit, and sometimes, it's cheaper.
    Check my worklog:
    Corsa + Atom + Gentoo Linux + 9" capacitive touchscreen

    Lord of the boards: DFI CP100-NRM

    "Or you can try Ubuntu, but than don't tell everyone you are using linux,
    because it's just a secret unreleased prebeta of Windows 3829" :P

    Tengis, you still owe everyone an answer whether you have confirmed that your amps are turned all the way down rather than turned all the way up. If anything, the onboard audio level is lower than a high quality head unit.

    Your own other thread on the same subject:
    http://www.mp3car.com/vbulletin/car-...ml#post1357355

    Other than that, I am happy with my mouse wheel based Windows volume control:
    http://www.mp3car.com/vbulletin/inpu...use-wheel.html
    64 bit worklog (Vista, 7, XP)

    When I fully crank up my volume, I get loud audio that's just below the threshold of clipping. This is girlfriend proof. When someone turns the volume all the way up, the tweeters are not fried and the ears don't bleed.

    Add on audio...

    Add on audio card will always be better than onboard ones since a good quality soudcard will have a dedicated audio processor, like the creative line. Also it doesn't hurt adding a software solution combined like (volumelogic) not longer supported but still available around.

    thats really not true anymore. just because onboard processes the audio in software, it doesnt not mean its worse then a hardware card (far from it!). whats kept onboard sound from being acceptable was the analog conversion chips, but with the latest packages like the ALC888 you can pretty much forget about the need for a seperate sound card.
